trirotor

There will be a central pod containing batteries and avionics, with a set of arms radiating from it, each of which will have a motor and a propeller on its end. You are almost certainly picturing a four-rotor design, such as the extremely popular DJI Phantom series of craft.

Of course, four-rotor designs are just one of many possible configurations of a multirotor. You will commonly see octocopters, but sometimes we’ve brought you craft that really put the “multi” in “multirotor”. If the computer can physically control a given even number of motors, within reason, it can be flown.

There is one type of multirotor you don’t see very often though, the trirotor. Three propellers on a drone is a rare sight, and it’s something we find surprising because it’s a configuration that can have some surprising benefits. To think about why, it’s worth taking a look at some of the characteristics of a three-rotor machine’s flight.

Once you realize you can make almost anything fly if you strap a big enough prop and motor to it, you really start thinking outside of the box. That’s what [Rodger] did and he’s come up with this very impressive 19lb, 5′ long X-Wing Fighter from Star Wars.

Recently [Rodger] has found new joy in making movie props come to life with the help of today’s technology. He started with Project Thunderball — a flying James Bond mannequin with a jet pack. From there he brought us the Marty McFly working hover-board, and now an X-Wing Fighter, his biggest flying machine yet.

It measures about 5 feet long, and is a tri-rotor design with three 100A ESCs, 1200W 1050KV motors, and 12″ rotors. The frame is made of PVC to conserve weight. Since it’s a tri-rotor with true vectored thrust, the X-Wing features much better yaw than quadrotors. Then only problem is it pivots around the odd prop out, meaning in this case, the X-Wing turns on its nose — instead of its tail.

Regardless, we can’t wait to see what [Rodger] tries flying next! Stick around to see the X-Wing in action.
